That is roughly how far I got but gschem "forgot" the entries after a while. Then I tried it again with a dual opamp. In order not to mess up too badly with a new CAD system I start with existing symbols and modify them. With the dual opamp my changes stuck. Well, to some extent (it forgot the slotdef changes after I copied that very same symbol). Now I am going to have to figure out how to make gschem find it in the menu. Eagle had a preferences menu that let you set directory paths. You could set that to a personal area, copy all the libs to that and then piece by piece replace things with your own symbols and footprints. I guess that steep learning curve must be tackled ... > I've attached a screenshot of the 74141 with all its attributes and > pin properties visible. > Thanks. It is nice that we can attach small pics here.
